Improved railroad-rail



UNITED STATES PATENT OFFICE.

ROBERT V. JONES, OF CANTON, OHIO.

IMPRov'l-:D RAILROAD-RAIL.

To all whom it may concern:

Beit known that L'ROBER'JJ V. JONES, of Canton, in the county of Starkand State of Ohio, have invented certain new and useful Improvements inRailroad -Rails5 and l do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the Vletters of reference marked thereon.

By reference to the drawings it will be seen that this rail is' made intwo parts, A representing the bottom or base of the rail, and B the top,the two parts, when secured together, resembling very much in appearancethe ordinary T-rail.

The upper part of the rail is provided with a tongue on its under sidewhich passes or sets into a groove in the lower part, A. The two langesDD, which form the sides ofthe grooves in the lower part, A, are beveledupon their upper edges so as to fit into V-shaped grooves on the underside of thepart B.

G represents a bolt, which passes through openings in the two partswhere they are joined in order to confine them together.

By reference to the drawings it will be seen that the tongue E hasacpeculiarity of construction which I will describe. Y From @c a:(points a little above the curved end of the tongue) to z z the tongueis made concave on both sides, and from z z to a a the thickness of thetongue is diminished gradually a little. For instance, if the thicknessofthe tongue is one inch and a sixteenth from z to z, the thicknessshould be decreased to one inch from a to a, making a decrease ofone-sixteenth.

The object in making the tongue concave on each side is, that when thebolt Gr is put through the two parts the two flanges D D may be sprungin a little to the tongue by means of the nut upon the end of the bolt,for the purpose of leaving spring-pressure upon the nut to prevent itfrom jarring loose by the continued vibrations of trains passing overit.

- The object in decreasing the thickness of the tongue from z to a is,-that when the train passes over or is upon the rail B its weight willcause the beveled edges of the grooves from c to c to press upon thecorresponding beveled edges of the anges and force the said flangestightly against the tongue. Forcing the anges at or near their upperends against the tongue, springing it slightly over the bulge at z,ei'ects the double object of binding the anges to the tongue, and thusmaking a tight joint, and also of causing a tendency of the flanges tospring out below the bulge at z, 'to more effectually prevent the nutwhich binds the two parts together from moving.

Whenthe train is upon this rail a tight joint is made between the twoparts by the weight of' the train, as has been stated. This preventsrattling of the rails. As soon as the train leaves the rail the twoparts of said rail, by their construction described, relieve then]-selves, and are sufficiently free to prevent damage from expansion orcontraction of the parts.

What I claim as new, and desire to secure by Letters Patent, is

The top rail provided with a tongue, E, upon each side o f which areV-shaped grooves, said tongue being made concave on its sides below itscenter, and decreasing in size or width from'z z to a a, when used withthe llanges D Dwith beveled edges and straight sides, sub stantially asand for the purposevherein speci- ROBERT V.
